Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77918, here are decompositions:
- 19 + 77899 = 77918
- 79 + 77839 = 77918
- 157 + 77761 = 77918
- 199 + 77719 = 77918
- 229 + 77689 = 77918
- 271 + 77647 = 77918
- 277 + 77641 = 77918
- 307 + 77611 = 77918
Showing the first eight; more decompositions exist.
